4 Claims. (01. 308-214) My invention relates to roller bearings, particmember and the portions of the cup bores beyond ularly to bearings adapted for uses where the theconical raceways 12 have the same taper as loads are heavy and the space available for bearsaid raceways. The outer raceway of said outer ings is limited. The bearing is especially adapted bearing member 9 has reversely coned portions 13 for useinrolling mills and other machines whereof the same taper as the bores oi the bearing in the bearing is mounted on a rotary shaft, roll members into which they extend; or spindle, the outer bearing member of the bear- Obviously by moving the conical bearing cups ing remaining stationary. 11 endwise, the taper rollers 4 may be adjusted The invention consists principally in a roller for wearand also the outer bearing member 9 bearing having two series of tapered rollers and oi the cylindrical rollers is reduced in size to com- 65 one or more intermediate series of cylindrical pensate f0. wear oi said cylindrical rollers 6. rollers, the outer bearing member of said cylin- Preferably the bearing is mounted in a rolling drical rollers being split likewise and having conimill or other device where the outer bearing cal outer surface portions fitting in the conical member is stationary; and e Split of said bores of the cups of said conical rollers.
